i used it in the specialist loadout and it helped me get a kem, the good news is that if you kill two enemys side by side you get double the pings which will help you locate the other enemys even more easily, overall ill say it is well worth the two points, but if your going against players using OTF then it is as good as useless
I personally find it very usefull on smaller maps such as free fall and freight were players are in closer proprieties. However on maps like Stonehaven its pretty much useless. So its more of a as needed perk.
you cant compare them cause one is a perk while the other is a streak, even so ill say the oracle is better
1. oracle can see through walls period
2. OTF does not counter oracle
OTF=OFF THE GRID which protects you from satcoms and pings but not from enemy oracle, died tons of times off of a streak cause the enemy saw me through the oracle
Blind Eye protects you from the Oracle, not that anyone ever uses it.
